FLY-TRAP.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed April 1,1907. Serial No. 365,670.

To all whom it may concern:

Be it known that I, GEORGE WILLIAM STEIN, a citi- I zen oi the United States, residing at Washington, Dis- 'ping ilies which is particularly simple in its construction and cheap and easy to manufacture.

It is well known that flies on the interior oi a building congregate in large numbers on the window panes and along the window sash in their endeavor to reach the outside; and I have found by experience that iies can be trapped in very much larger numbers at or near a window in a building than at any other locality. I have therefore designed a simple ily trap which is arranged on the window pane and against the inner edge oi4 the window sash in such manner that the same is scarcely visible or noticeable either from the inside or outside o the window, at the same time this particular location oi the trap'is arranged directly in the usual path oi the iies thereby making it possible to trap a larger number oi iiies and in a shorter period oi time than ii the same trap were located on the window or sash.

My invention consists in the novel construction oi the iiy trap as will be first fully described and afterwards speciiically pointed out in the appended claims.

Referring to the accompanying drawing: Figure l is a fragmentary view of a portion oi a window pane and sash showing two traps in operative position. Fig. 2 is a vertical sectional View through a portion oi a window pane and sash taken on line 2-2 oi Fig. l. Fig. 3 is a vertical longitudinal sectional view through one oi the cone shaped entrances oi the trap. Fig. 4 is a vertical longitudinal sectional view oi one oi the ends oi the trap. Fig. 5 is a vertical transverse sectional view through the trap taken on line 5-5 oi Fig. 4. Fig. 6 is an elevation partly in section showing a trap made of paper, and Fig. 7 is a vertical longitudinal sectional view through a .portion oi the trap showing receptacle holding a poisonous liquid.

Like numerals oi reference indicate the same parts throughout the several figures in which;

l indicates the window pane, 2 the window sash and 3 the trap.

As shown in Fig. 1 the trap may either be rectangular in order to lit snugly against a corner of the window pane one portion oi the trap extending along the vertical portion of the sash and the other portion `extending along the horizontal portion oi the sash or itmay be straight in form in order to iit snugly `against the side oi the window pane and against the inner edge oi the sash, either along the said top or bottom oi the sash. l

The trap 3 is preferably constructed oi a suitable wire screen although it may be made oi paper or other suitable material as shown in Fig. 6. In any event it is formed in cross sections substantially as shown in Fig. 5, having a vertical wall 4 which rests against the window pane and a flat bottom 5 which rests against the inner edge oi the sash and the curved side 6.

As shown, the ends 7 oi' the trap are preferably inclined and arranged to receive a cone shaped entrance 8, said cone shaped entrance having a reduced inner end 9 and inwardly extending wires or prongs l0 so as to allow easy entrance oi the ih'es and to prevent ready exit o the ilies from the trap. The outer end ll oi the entrance 8 is preferably inclined to conorm to the inclined end 7 oi the trap, and a small wire or handle 12 is provided in order to allow the entrance 8 to be readily withdrawn manually ior the purpose of emptying the trap. I

As shown in Fig. 7 whenever the trap is arranged in the bottom edge of the window pane it is sometimes desirable to insert a small receptacle 1310i poisonous liq' uid or other material therein so that the flies when entering the trap will be killed, thereby rendering the emptying oi the trap much easier. Ii desired a strip oi iiy paper l5 can be inserted on the bottom o the trap as shown in Figs. 4 and 6;

As shown in Fig. l one or more small brads I4 can be utilized for securely holding the trap in position against the edge of the sash.

Having thus fully vdescribed my invention what I claim as new and desire to secure by Letters Patent oi the United States isz- 1. A ny trap for use alongl the edge of a Window pane having a flattened portion to lie against the Window pane and a flattened portion to lie against the window sash, the ends of said trap being inclined, and a removable cone shaped entrance arranged in one of the said inclined ends of the trap, substantially as described.

2. A fly trap formed to fit a corner of a window sash having one portion thereof extending along;` the vertical part of the sash and tting snugly thereon, and the other portion of the trap extending along the horizontal portion of the sash and fitting snugly thereon, and a 'cone shaped entrance for said trap, substantially as described.-

In testimony whereof, I afx my signature, in presence of two witnesses.

GEORGE WILLIAM STEIN.
